Celebrity Big Brother bosses have been forced to step in after Bobby Sabel gave fellow housemate Darryn Lyons his sweat to drink.

The model was supposed to pour water over the paparrazo’s head in a Wizard of Oz task – in which Darryn played the tin man who needed ‘oiling’.

However Bobby visited the house sauna where he collected perspiration from his armpits in cotton balls and then squeezed the sweat into a watering can, which he gave the Australian to consume.

Bobby has been warned about his conduct on the Channel 5 show â which features reality star Kerry Katona , former The Only Way is Essex beauty Amy Childs and American Pie actress Tara Reid â following the incident, which he bragged about afterwards.

He said: ‘I greased him good.’

But the 25-year-old model confessed to Darryn about what he had done and apologised for his actions.

A Celebrity Big Brother spokesperson said: ‘Bobby has spoken to Big Brother about what he did to Darryn. He is remorseful and has now apologised.’

The joke did not go down well with other contestants, with his close friend in the house Lucien Laviscount describing the prank as ‘disgusting’.

Paddy Doherty was also not impressed, saying: ‘I wouldn’t like a man to come and wise crack like that with me. I won’t wear it. I’d be fired up.’
